4 Claims.

guishing features and advantages will appear when the following specification is read in connection with the accompanying drawings, in

which- Fig. 1 isa perspective .view showing a lifeboat boomed on in an outboardposition in accordance with the present invention.

Fig. 2 is an end view of the booming olevice, the boom being shown in full linesin an inboard position, and theboom. also being shown inv dotted lines in an outboard-booming position.

Fig. 3 is a fragmentary top plan view.

Fig. 4 is a sectional view taken onthe'line 2-4 of Fig. 2.

Referring now to Figldt will be seen there are shown a lifeboat ll), davits H pivotally connected adjacent the fish plate or edg of a. ships deck l2, gear l3 supported by the davits and connected with the lifeboat for lowering and raising the lifeboat, and chocks it on the deck l2. Thedavits ii are swingably mounted for the purpose of swinging the lifeboat between an inboard and an outboard position with respect to the deck 12.

Means it are provided for swinging the davits forthe statedpurpose.

In accordance with the present invention, a

it of any suitable length and cross-sectional size and shape is rigidly supported at the ends thereof on th upper ends of arms ill bea tween the arms. Eacharm :il consists of aT iron in the persent instance, and each is cut away to provide an unflanged'lower end portion. A cross-piece i8 is securedto the upper end of each arm H and a clip lllengaged with the related end of the boom iifi is. secured to the crosspiece id, as at 2E]. A brace 2! is connected with the arms 11 between them. The lower end of each arm l? is pivotally connected, as at 22, with a channel iron 23, or other suitable attachment, anchored to the deck ii in any suitable manner. The channel iron 23 has a longitudinal slot 25 therein to accommodate the lower end portion of the related arm ii. Th slot terminates short of both ends of the channel iron 23.

A bracket 5' 25 is welded or otherwise secured to .the top of each channel iron 23 intermediate the ends thereof. The bracket ,25 provides spaced plates 25 and a stop 12:l betvveen the plates. These plates are upstanding at opposite sides respectively of theslot 24.

The boom it has pads 0r cushions 28. Each pad :or cushion may be of any suitable type, and in the present instance consists of a bag structure of stout fabricsuchas canvas, filled with sawdust, cork or equivalent material.

In order to retaintheiboo-m .ljfi'inthe active or booming position, the-plates 26 of each bracket '25 have a pair or pairs of registering holes 29 5 therein which receive a .pint39 While extending through a hole ,3 I in the related arm l1.

Thelifeboat isyretained ainboardresting on the checks i4 and held thereon by suitable gripes or other means attached to the :deck and v the lifeboat, together .withmeans on the deck detachably engaged with the-keel of the-lifeboat. When the lifeboat is :in' the inboard position, the boom rests idly on the heck, as'shown in Fig. 2, be-

tween the checks 1.4.

When it ,is desired :to boom the lifeboat outboard for emergency zpurposes, Ithe ;lifeb oat is freed and the gdavits ll swung outward to carry the lifeboat into an.outboardposition-beyond the fish plate or edge of the deck 12. 'The'boom it then maybe; quicklycandaeasilyqswung to a booming positioninwhichzthespadsfifi:contact the side of '"the'lifeboat. The .pins :39 are thrust through theplates 126 and=the;arms H by reason of the holes -29 and-.31 to .holdthe boom in set position.

SuitableilashingrS-Z attached to-the lifeboat and the deck [.2 cooperate .with the'boom It to prevent the lifeboat from movingzlaterally or swaying. Inthis manner :the .lifeboat is effectually boomed in the outboard "position ready for an emergency, as'shownin- Figgl. The booming operation may be accomplished quickly and with a minimum oflabor,

The stops 2'! cooperating .withthe arms I! respectively prevent them :from swinging outwardly too far and make .it .easy 'to insert the pinsflfi.

I claim:

1. In an apparatus for booming into outboard position, a lifeboat connected at its ends by tackle to the upper ends of two davit stanchions from an inboard position on chocks disposed between said stanchions and spaced inboard of said stanchions, the stanchions extending upwardly from the edge of the deck, and the upper ends thereof extending outboard of the edge of the deck in outboard position, of a pair of brackets secured to the deck of the vessel disposed between said stanchions and spaced inboard of said stanchions, but outboard of said chocks, said brackets each including an outwardly inclined shoulder, a pair of arms each pivotally connected at its lower end to one of said brackets and movable from an inwardly extending position to an outwardly inclined position where it is resting on one inclined shoulder, said brackets being also disposed closer together than said chocks, a boom connected to the outer free ends of said arms, and two pads spaced from one another and mounted on said boom to engage the side of the lifeboat when said arms are resting on said shoulders in an outward position whereby the supporting strain of the lifeboat in outboard position in part is transmitted directly to the deck, said boom, pads and arms in inboard position lying between said chocks.

2. In an apparatus for booming into outboard position, a lifeboat connected at its ends by tackle to the upper ends of two davit stanchions from an inboard position on chocks disposed between said stanchions and spaced inboard of said stanchions, the stanchions extending upwardly from the edge of the deck, and the upper ends thereof extending outboard of the edge of the deck in outboard position, of a pair of brackets secured to the deck of the vessel disposed between said stanchions and spaced inboard of said stanchions, but outboard of said checks, said brackets each including an outwardly inclined shoulder, a pair of arms each pivotally connected at its lower end to one of said brackets and movable from an inwardly extending position to an outwardly inclined position where it is resting on one inclined shoulder, said brackets being also disposed closer together than said chocks, a boom connected to the outer free ends of said arms, two pads spaced from one another and mounted on said boom to engage the side of the lifeboat when said arms are resting on said shoulders in an outward position whereby the supporting strain of the lifeboat in outboard position in part is transmitted directly to the deck, said boom, pads and arms in inboard position lying between said chocks, and pins in said brackets for anchoring said arms in outward position.

3. In an apparatus for booming into outboard position, a lifeboat connected at its ends by tackle to the upper ends of two davit stanchions from an inboard position disposed between said stanchions and spaced inboard of said stanchions, the stanchions extending upwardly from the edge of the deck, and the upper ends thereof extending outboard of the edge of the deck in outboard position, of a pair of brackets secured to the deck of the vessel disposed between said stanchions and spaced inboard of said stanchions, said brackets each including two side plates and an outwardly inclined shoulder, a, pair of arms each pivotally connected at its lower end to one of said brackets and movable from an inwardly extending position to an outwardly inclined position where it is disposed between one pair of side plates and resting pads spaced 4 on one inclined shoulder, a boom shorter than the lifeboat to be boomed connected to the outer free ends of said arms, and pads spaced from one another and mounted on said boom to engage the side of the lifeboat when said arms are resting on said shoulders in an outward position, said stanchions and brackets being remotely spaced from one another to facilitate independent handling of the boom and tackle without danger of interference whereby the supporting strain of the lifeboat in outboard position in part is transmitted directly to the deck, said boom, pads and arms in inboard position lying between said chocks.

4. In an apparatus for booming into outboard position, a lifeboat connected at its ends by tackle to the upper ends of two davit stanchions from an inboard position disposed between said stanchions and spaced inboard of said stanchions, the stanchions extending upwardly from the edge of the deck, and the upper ends thereof extending outboard of the edge of the deck in outboard position, of a pair of brackets secured to the deck of the vessel disposed between said stanchions and spaced inboard of said stanchions, said brackets each including two side plates and an outwardly inclined shoulder, a pair of arms each pivotally connected at its lower end to one of said brackets and movable from an inwardly extending position to an outwardly inclined position where it is disposed between one pair of side plates and resting on one inclined shoulder, a boom shorter than the lifeboat to be boomed connected to the outer free ends of said arms, from one another and mounted on said boom to engage the side of the lifeboat when said arms are resting on said shoulders in an outward position, and pins in said side plates for anchoring said arms in outward position, said stanchions and brackets being remotely spaced from one another to facilitate independent handling of the boom and tackle without danger of interference whereby the supporting strain of the lifeboat in outboard position in part is transmitted directly to the deck, said boom, pads and arms in inboard position lying between said chocks.
